This module is superior to the SoundGenerator module, which can only play a single sound at the desired frequency for the desired duration. The MelodyPlayer module is equipped with a ROM that contains music notes and their length of time. After starting the module with the Play signal, the module reads consecutive sounds from the memory and pushes them to the SoundGenerator. This way, a melody player with capabilities similar to the ringtone composer from the Nokia 3310 can be realized.

		.CLOCK_HZ(CLOCK_HZ)
	) DUT(
		.Clock(Clock),
		.Reset(Reset),
		.Play_i(),
		.Stop_i(),
		.SoundWave_o()

• Reset - Asynchronous reset, active low.
• Play_i - A high pulse triggers the start of melody playback.
• Stop_i - A high pulse stops the operation.
